What is Newton's 1st Law?
An object in motion stays in motion, an object at rest stays at rest, unless acted on by an unbalanced force.
Force = Mass x Acceleration
For every force, there is an equal and opposite force.
What is Newton's 2nd Law?
An object in motion stays in motion, an object at rest stays at rest, unless acted on by an unbalanced force.
Force = Mass x Acceleration
For every force, there is an equal and opposite force.
What is Newton's 3rd Law?
An object in motion stays in motion, an object at rest stays at rest, unless acted on by an unbalanced force.
Force = Mass x Acceleration
For every force, there is an equal and opposite force.
Inertia depends only on...
shape
weight
applied force
mass
Inertia is...
An applied force.
The tendency of objects to resist change in motion (keep doing what their doing).
A type of acceleration.
A type of friction.
Which object has the MOST inertia?
A ping-pong ball.
A golf ball.
A tennis ball.
A bowling ball.

act alone.
come in pairs.
are always perpendicular.
come in groups of four.
For every force, there is an equal and opposite force. What is EQUAL?
